Other Proteins that contain the ADF homology domain

Other Proteins that contain the ADF homology domain.

A number of other actin binding proteins with properties distinct from the ADF/Cofilin family exist (Table 1).

Protein	Function	References
Abp1p	A mulitfunctional protein involved in the Golgi cytoskeleton, endocyotosis and Arp2/3 activation.	Goode et al, 2001; Holtzman et al, 1993; Jeng & Walsh 2001
Coactosin	A protein originally discovered in yeast but now found in humans where it binds 5-lipoxygenase	de Hostas et al, 1993; Provost et al 2001a & b.
Drebrin	A group of 95- 100kDa actin-binding proteins that are especially enriched in brain	Hayashi et al, 1999; Peitsch et al, 1999.
Twinfilin	An actin monomer sequestering protein that contains two ADF homology domains.	Goode et al, 1998; Palmgren et al, 2001, 2002; Wahlstrom et al, 2001.
